Abstract: A thin flexible fluid-tight cover (12) of PVC is bonded to a rigid port (20) of a diluent container (8) which is to be subjected to heat sterilization. The cover (10) includes an outer flange (50) for bonding to a complementary surface (55) around the port (20), and a removable section (60, 62) for spanning the port (20). The removable section includes a central flexible diaphragm portion (57) and a cylindrical wall portion (60). The diaphragm portion (57) has at least one annular convolution whereby the diaphragm section (57) is axially expandable by flexing of the convolution. A tear line (58) is provided in a frangible section which joins the cylindrical wall portion to the outer flange. The cylindrical wall portion of the cover is disposed adjacent the outer surfaces of an abutment wall on the port to provide stress relief against rupture of the tear line from stresses generated in the cover during sterilization. A narrow post (82) element is located adjacent the wall portion for concentrating manual pulling forces from an attached pull ring (76) to a limited segment of the tear line (58).

Abstract: Method and apparatus for quieting the operation of a dot matrix printer by logically dividing the data to be printed among timed spaced printing passes. A matrix of data to be printed is stored in a memory. A slice of data is selected from the stored data and the number of dots to be printed simultaneously is reduced by logically allocating the data in each slice among complementary submatrices. Each submatrix of data is printed substantially aligned with each other submatrix in two passes of the print head across the print medium to represent the entire selected slice of data. Noise reduction is achieved by reducing the number of data dots simultaneously printed at each print location

Abstract: In known arrangements for inserting data into a video signal, the clock signals generated in a text generator are phase-locked to the synchronising pulses of the video signal so that the data signals formed in the text generator can be accurately synchronised with the video signal. However, if the video signal has a severe timing error, this can lead to the data signal to be inserted no longer being readable. The novel arrangement is to provide the possibility for the data signal to be displayed without jitter and readably even when the data signal is inserted into a video signal with severe timing error.   For this purpose, the synchronising pulses with timing error are used for forming horizontal synchronising pulses without timing error as reference in the text generator and these are inserted together with the data into the video signal with timing error.
